热处理钢、合金钢和易切削钢 第 6 部分：调质弹簧用热轧钢

[中文适用范围]： 本文件规定了用表 4 所列合金钢制成的圆钢、扁钢和线材的交货技术要求，这些钢用于热成型并随后进行热处理的弹簧或冷成型并随后进行热处理的弹簧。产品以表 2 中为不同类型产品所给出的热处理状态和表 3 中给出的表面状态之一供应。注 1：表 4 仅考虑了具有一定国际重要性的钢材。但这并不意味着所有工业国家都有这些钢材。此外，区域和国家标准中还规定了许多其他钢材。注 2：用于生产弹簧的非合金钢也包含在表 4 中的线材规范中。注 3：与符合表 4 中的化学成分要求但以其他产品形式或其他处理条件供应或用于特殊用途的钢材有关的国际标准在参考书目中给出。 [外文原描述]： This document specifies the technical delivery requirements for round and flat bars and wire rods manufactured from the alloyed steels listed in Table 4, intended for hot-formed and subsequently heat-treated springs or cold-formed and subsequently heat-treated springs. The products are supplied in one of the heat-treatment conditions given for the different types of products in Table 2 and in one of the surface conditions given in Table 3. NOTE 1 Table 4 only considers steels that have gained certain international importance. This does, however, not mean that these are available in all industrial countries. In addition, a great number of other steels are specified in regional and national standards. NOTE 2 Non-alloy steels also for the production of springs are covered by the wire rod specification in ISO 16120-4. NOTE 3 International Standards relating to steels conforming with the chemical composition requirements in Table 4, but supplied in other product forms or other treatment conditions or intended for special applications, are given in the bibliography.
